The difference between oled TV and led TV

1, the working principle is different

LED is the use of solid semiconductor chips as light-emitting materials, when the two ends of the positive voltage, the carriers in the semiconductor composite caused by photon emission and produce light.

OLED working principle is to use ITO glass transparent electrode and metal electrode as the device's anode and cathode, respectively, driven by a certain voltage, electrons and holes were injected from the cathode and anode into the electron transport layer and hole transport layer, respectively, migrate to the light-emitting layer, meet the formation of excitons to make the light-emitting molecules excitation, which is emitted by the latter after radiation of visible light.

2.? Fast response time

OLED and the use of the most common compared to LCD, with a thin panel, high contrast, fast response time, low power consumption, wide viewing angle, light weight, etc., especially worth mentioning the advantages of the OLED screen can be bent, folded, and even like a piece of paper hanging on the wall, placed in a pocket, or even inlaid in the clothes, when not in use is a part of the clothes, and when needed can be The new technology will be able to display the necessary information when it is needed.

3, different color gamut

LED can only be applied in the form of point light source, can directly emit red, yellow, blue, green, cyan, orange, purple, white light.

While OLED is driven by current to the organic film itself to emit light, OLED is an inherent surface light technology, no backlight, each pixel is independent of the self-emitting light, light can be red, green, blue, white and other monochromatic, and then achieve the effect of full color.
